Texas hires ex-GM Purpura as farm director

ARLINGTON -- The Rangers have hired former Astros general manager Tim Purpura as their farm director.

Purpura, who is currently the chief operating officer for Minor League Baseball, will replace Scott Servais, who left the organization to be the assistant general manager for the Angels.

"This was an opportunity to add an experienced baseball person, somebody who has done a lot of different things in the game," Rangers general manager Jon Daniels said. "He brings a unique skill set. He has a law degree and 20 years of experience in player development.

"He brings a unique element to the organization and will complement our player development team. We have some good people in that department and Tim will bring out the best in them."

The Rangers seriously discussed the possibility of having assistant general manager Thad Levine add the duties of farm director to his responsibilities. But the Rangers decided he was too valuable in his current role as Daniels' No. 1 assistant and did not want to spread him too thin.

Purpura was the Astros' assistant general manager from 1997-2004 and oversaw the farm system. He served as GM from 2005-07, during which the Astros went to the World Series in '05. He has a close relationship with Rangers club president Nolan Ryan, who owned two Astros farm teams during Purpura's time in Houston. Ryan also worked as a special assistant with the Astros while Purpura was the GM.

During Purpura's time, the Astros went to the playoffs six times in nine years from 1997-2005 and were named Major League Baseball's Organization of the Year by multiple entities in 2001. He is entering his 23rd year of working in professional baseball.

The Rangers have also promoted Jayce Tinger to Minor League field coordinator. Tingler, 31, will be in his sixth season in the Texas organization in 2012.  He spent last season as Coordinator of Instruction for the club's Arizona and Dominican Republic operations.  He served as the organization's manager in the Arizona League (2010) and Dominican Summer League (2008-09), leading clubs to first-place finishes in each of those three years.
